WAVE-MOTOR.

Specification of Letters Patent. Patentad 15131; 28, 191 5.

Application filed November 21, 1914. Serial No. 813,665.

more particularly to motive apparatus adapted to be actuated byboth the rise and the fall of a boat, barge, 01- any suitable float placed on water subject to waves or to a rise and drop of the water level. One object of the invention is to provide novel and improved motive apparatus which is' mounted on a platform andincludes a pulley which is operatively connected by two cables to a boat, barge, or any'suitable float, so as to be actuated by both the rise and fall of the boat, barge, or suitable float.

Further objects of the invention are to provide a novel andimprovedwave' motor which is simple and economical to construct, install, and maintain, strong and durable, easy and convenient to operate, and efficient in action. a

With the above and other objects in View which will be apparent to those skilled in the art, the invention may be said to consist in the provision of the novel and advantageous features and in the novel and improved construction, arrangement, and combination-of parts hereinafter described and illustrated in the accompanying drawings which show preferred forms of construction and in whicha Figure 1 is a broken plan view of the wave motor; Fig. 2 is a sectional view taken on the line 22 of Fig. 1; Fig. 3 is an enlarged broken plan view of a portion ofthe motive apparatus; Fig. a is a sectional view taken on the line 41 of Fig. 3; Fig. 5 is a sectional view taken on the line 5-5 of Fig. 3; Fig. 6 is an enlarged broken sectional view taken 011 the line 6-6 of Fig. 5; Fig. 7 isa sectional view taken on the'line 7-7 of Fig. 3; Fig. 8 is a sectional view taken on the line 88 of Fig. 3; Fig. 9 is an enlarged broken and sectional view taken on the line 99 of Fig. 2; Fig. 10 is a broken plan view of a modified construction for the wave motor; and Fig. 11

-is a broken sectional view taken on the line -1111 of Fig. 10.

As shown in the drawings, the boat, barge, or suitable float 12 has suitably mounted thereon the rollers 13 which are adapted to contact with-the substantially vertically guides 14 which latter are secured to a framework preferably consisting of crosspieces 15 fastened to piles 16 driven into the ground '17 under the water 18 in which the float 12 is placed.

A pulley 19 is mounted on a shaft 20 which latter is mounted on a frame 21 suitably secured to the platform 22 adjacent .to the float 12.

Two cables 23 and 24 are operativcly connected with the pulley l9 andthe float 12; said cables each having one end thereof secured to the pulley 19 and passing thereover inthe grooves 25 andthe cable 23 being adapted to operate thepulley 19 when the float 12fa'lls and the cable 24 being adapted to operate the pulley 19 when said float 12 rises. The other end of the cable 23 is preferably wound on a reel 26 which is suitably secured to the" float 12 and has thereon the handle 27, pawl 28, and ratchet 29; and the other endportion of the cable 24 is arranged in contact with a sheave 30 and is suitably secured to the float 12. To the sheave 30 is secured one end of a cable '31 which is arranged in contact with a connected the rods 35 of pistons 36 which are arranged in the cylinders 37 of suitable pumps; or as shown in Figs. 1 and 2, the pulley 19 may be mounted loose on the shaft 1 20 between the pulleys 38 which latter are also mounted loose on the shaft and operatively connected with the pulley and have thereon the belts 39. The pulley 19 has at the sides thereof the ratchets 40 which coact with pawls 41 which latter are pivotally mounted on the pulleys 38 and pass through yoke guides 42 mounted on the pulleys 38 adjacent to the pulley 19. Springs 43 9 1 the pulleys 38 press the pawls 4.1 into be readily understood by those skilled in the art. It will be seen that the cables 23 and 31'may be adjusted by turning the reels 26 and 26 respectively, and that the cable 23 operates the pulley 19 when the float 12 falls, and the cable 2 1 operates said pulley 19 when said float 12 rises. When the pulley 19 is turned in one direction one of the pulleys 38 is turned with it by reason of the pawl 41 thereon engaging with one of the ratchets 40 on said pulley 19, and whenthe latter is turned in the other direction the other of the pulleys 38 is turned with it by reascn of the pawl 11 thereon engaging with the other of the ratchets 40 on the pulley 19. When the pawl 41 on one of the pulleys 38 engages one of the ratchets 10 and such pulley 38 is consequently turned by the pulley 19, the pawl 4-1 on the other of the pulleys 38 rides freely over the other of the ratchets 40. y l

The forms of construction which have been particularly illustrated and described admit of minor changes and modifications, wherefore the right is reserved to all such changes and modifications as do not depart from the spirit and scope of the invention which is defined in the appended claim.

I claim:

The combination of a float, a shaft, a pulley loose on the shaft, a reel on the float, a cable secured to said pulley and connected With said reel, a sheave, a cable in contact with said sheave and having one end thereof secured to said pulley and having the other end thereof secured to said float, an anchor, a sheave mounted on the anchor, a-reel, a cable in contact with the last mentioned sheave and having one end thereof connected with the last mentioned reel and having the other end thereof connected with the first mentioned sheave, pulleys arranged loose on said shaft at the sides of said pulley, ratchets on said pulley, yoke guides on said pulleys, pivoted pends on said pulleys adapted to ccact with said ratchets and passing through theyoke guides,a frame, ratchets on said pulleys, and pawlspivotally mounted on said frame and adapted to coact with the last mentioned ratchets, substantially as described.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses at Los Angeles, county of Los Angeles, State of California, this-14th day of November, A. D. 191d.
